docker 安装ElasticSearch

安装ElasticSearch

1. 下载ES镜像

docker pull elasticsearch:7.17.3

​

• 创建映射文件

 mkdir -p /usr/local/elasticsearch/conf
 mkdir -p /usr/local/elasticsearch/conf
 mkdir -p /usr/local/elasticsearch/data

• 创建elasticsearch.yml

vi /usr/local/elasticsearch/conf/elasticseach.yml

# 允许外部访问
http.host: 0.0.0.0

• 授权

chmod -R  777 elasticsearch/

• 启动容器

docker run --name elasticsearch -p 9200:9200  -p 9300:9300 -e "discovery.type=single-node" -e ES_JAVA_OPTS="-Xms84m -Xmx512m" -v /usr/local/elasticsearch/conf/elasticsearch.yml:/usr/share/elasticsearch/config/elasticsearch.yml -v /usr/local/elasticsearch/data:/usr/share/elasticsearch/data -v/usr/local/elasticsearch/plugins:/usr/share/elasticsearch/plugins -d elasticsearch:7.17.3

• 检查容器启动日志

docker logs -t -f elasticsearch

2. 下载ES Header

• 拉取镜像

docker pull mobz/elasticsearch-head:5

• 启动

docker run -d --name es-head -p 9100:9100 docker.io/mobz/elasticsearch-head:5

• 重新配置elasticseach.yml

vi elasticsearch.yml


# 设置支持ES-Header
http.cors.enabled: true
http.cors.allow-origin: "*"

• 重启es容器

docker restart elasticsearch

• 访问ip +9100

报错解决

挂在时宿主机目录的权限不够。重新配置权限后重启es

chmod -R  777 elasticsearch/
